Abstract

A beam propagation through astigmatic square-law waveguides (n(x,y) equals K_x²X² + K_y²Y²) is investigated by theoretical and experimental means. It is shown that if certain condition between astigmatic value, length of waveguide, wave-front curvature and Gaussian parameters takes place then a Hermite-Gaussian beams transforms into Laguerre-Gaussian beams without residual astigmatism.
